A lot depends on the complexity of the board/process as well as the amount of placements. If the board has few placements and the parts are not smaller that 0805 then doing all the rework after completion is ok. The human eye can only pick out obvi

We are doing a field study to test the placement accuracy and calculate cpk of some machines in our plant. From previous readings, it is suggested that you buy glass board kits from Accuspec, Topline, etc. Is that the easiest/cheapest way to go abo

Hi Jack, I do not know what type of machine you are using and how old is your machine. But I have this problem before using Fuji machine. There are few things cause part throw.....placment speed, feeder, pick up tolerance, part dimension tolerance,

Hello EC, Thank you very much for the good input. I really appreciated. Our mounnters is Panasonic CM402,CM301. Do you have any suggestions/procedure how to reduce the sources of variance at each step of component placement process? regards,

We're soon to build a lead free assembly with 0201 components. I'm not worried about placement as our machines can handle it. Any tips on printing, screens, reflow?

Would you recommend a Yamaha Pick and place? In terms of reliability, accuracy, cph? We're looking for a pick and place that can deliver a 50 micron accuracy. What brands do you recommend for high accuracy placements?

Look into a used Siemens F-4 or F-5. These machines can be had for a reasonable cost, they are easy to maintain, the footprint is small (7' X 7.5') and they are simple to program. These machines have a 12 nozzle "Star" revolving placement head for
